To all whom) it concern:

Be it known that I, :EDWARD F. KUNATH, a citizen of the United States, residing in J ersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is aspecification. This inventi n relates to the accent-key 1o mechanism in which the ribbon is caused to vibrate at each type-stroke to cover nd uncover the rinting-point. In such achines the ribon-vibrator is 0 erated in the usual manner by a universa bar, and the latter is 0 erated, as usual, by all the type-keys, inclu ing the accent-type keys;

but each of the latter controls means for preventing the carriage from being fed by the operation of the uni- 2 versal bar, whereby it becomes practicable by striking one or more accent-keys before the ordinary type-key to secure the pro er register of the accent or accents above or elow the letter upon the written sheet.

In carrying out my resent improvements 1 provide upon the universal bar of the wellknown Underwood type-writing machine a trip which under normal conditions serves to transmit movement from the universal 3 bar to the usual carria e-feeding mechanism, the'latter being rovi ed with an abutment which is engage by said trip. To the accent key or keys, however, I connect means for intercepting said trip and causing it to swing to ineffective position, so that the universal bar is rendered incapable of moving the carriage-feeding mechanism out ofnormal position, and hence of the accent key or ke s no feeding of the carriage is effected, although the ribbon is vibrated, as usual, by the universal bar.

In the accompanying drawings, Figure 1 is a pcrs ective view of my improvements as applie to a universal bar and accent-type key in an Underwood front-strokewritingmachine. Fi .2 is a plan showing the trip on the universal ar-as swung to an inoperative position and also illustrating how the trip may be controlled by any of a plurality of accent-type keys.

An accent-type 1 is fixed-upon a type-bar 2, mounted u on a fulcrum-rod 3-and engaged by a bel -crank '4, the latter pivoted to a lever5, having 'of those type-writing machines 3 an accent-key 6 and pivoted at its rear end at 7. The levers and bellcranks for the ordinary types are indicated at 8 and 9, respectively. A depressionof the bell-crank forwardly, the type-bar rearwardly, through a ribbon 10'against a platen. (Not shown.) Each of the series of ty e-bars hasa heel 11, which strikes a curve universal bar' 12 and moves the same rearwardly, the universal bar being fixed upon a horizontaltable or frame 13, which in said machine is suitably guided for rearward and forward move ments. Upon said table 13 is usually fixed a slotted actuator 14, which engages a wrist 15, provided upon a short arm 16 of a lever 17, whereby the thereby throwing the type striking the front side of and down a vibrator 18, through which 18 threaded the ribbon 10. The ribbon is vibrated at the actuation of all the type-keys, including the accent-key. Said universalduring the operation I bar frame 13 is also utilized to effect the feeding of the platen-carriage, eluding a rack 19, meshing with a inion 20, connected to an escapcment-whee 21, with which cooperate the usual spacin and detent dogs 22 and 23, said dogs usua ly mounted upon an upright rock-arm 24. The backiri this instance b a trip 25, pivoted at 26 upon the to' su ace of the universal-bar frame 13 an having near. its rear end a slot 27, which engages astop-screw 28, said screw also preventing the rear end of the trip from lifting. off from said frame 13.

The rear end or tip of the trip on ages an abutment 29, projecting forwardly cm the rock-arm 24, said abutment being in the form of a screw, so as to be ad'ustable, thereby. to secure accurate and rapi feedin of the carriage. The trip under norma conditions engages said a 'ustable abutment at each rearward movement of a type-bar or of the universal-bar frame, so as to effect the usual feeding movement of the carriage. Said trip, however, is provided with an arm 30, and movable into the path of said arm is a etc or intercepter 31, mounted upon a rock-sha 32 and normally out of use, as seen at Fig. 1.
